HENRY I. HARRIMAN, OF NEW YORK, N. Y.

LOOM.

SPECIFICATION forming part of Letters Patent No. 653,178, dated July 3,1900. Application filed March 28,1900. Serial No. 10,439. (No model.)

T0 all wiz/0771, t may concern:

Be it known that I, HENRY I. HARRIMAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a certain new and useful Improvement in Looms, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

The invention has relation to looms of that class in which replenishmentof the Working weft-supply is effected automatically by the mechanism ofthe loom when necessity arises therefor- 21s, for example, on exhaustionof the supply of weft or filling that is carried by the Working shuttleon the lay or on exhaustion thereof to a predetermined extent `or onloss of continuity of such action of the replenishing instrumentalitiesbeing brought about or instituted through the agency of suitable formsof weft-indicatormechanism.

Looms of the foregoing class are presented' in United States LettersPatent granted to me June 13, 1899, No. 626,834; October 31, 1899, No,636,228; November 14., 1899, No. 637,113, and December 26, 1899, No.639,975. A loom of the said class is furnished with a reserve supply ofweft, which supply is drawn upon in accordance with the needs of theloom by the automatic replenishing instrumentalities. The said supply iscontained in a holder of appropriatecharacter, which last is arrangedand mounted conveniently in the loom. In the looms of my patentsmentioned above this holder consists of a hopper or magazine, which islocated at one end of the breast beam. The holder usually is capable ofcontaining a reserve supply of weft sufficient to permit thereplenishing instrumentalities to act several times in successionwithout eX- hausting such supply. For instance, when the loom is fittedto eii'ect replenishment by substituting a properly filled and threadedreserve shuttle in lieu of the spent or failed working shuttle on thelay the holder is adapted to contain a plurality of reserve shuttles,all prepared in readiness to be brought successively into service incontinuing the weaving. In practice the attendant weaver places in theholder what he regards 'as an adequate quantity of reserve weft to meet|`the usual exigencies and from time to vweft or filling, the

time makes such additions as seem called for in order to maintain thesupply and enable the loom to continue weaving uninterruptedly. Thenecessity for keeping properly charged the holders for reserve weft in.connection with all the looms of the entire number under the care of theweaver, which number is sometimes quite large, imposes quite a tax uponthe weaver, since it involves looking closely after the condition of thecontents of all the holders, which ordinarily can be done only bycontinued traveling about from loom to loom for'purposes of inspection.Occasionally the reserve supply of weft in a given loom is drawn uponquite iapidly--as, for instance, when several failures of weft followone another in close succession in .such loom or the weaver may bedetained by some duty at a particular point or points in the series oflooms under his charge. It thus may happen that the reserve supplycontained in a given holder becomes exhausted. If-now breakage orfailure of the working weft-supply occurs in the particular loom'towhich such holder pertains before the weaver renews the reserve supply,the lack of :reserve weft will prevent replenishment from being effectedautomatically, although the replenishing instrumentalities will becalled into action. 4

One object of the invention is to aid the lweaver and reduce thepossibilities of oversight by apprising him whenever the reserve supplyof weft is in need of renewal in any particular one or more of theseries .of looms under his charge.

Another object thereof is to enable the weaver when unable to giveimmediate attention to the particular loom in which the reserve supplyhas become exhausted to bring about at will the arrest of the workingthereof even when stationed for the time being at some distant pointamong the saidseries.

the replenishing instrumentalities when the l reserve supply of weft isexhausted or otherwise not in condition to enable replenishment to beeffected. l

In the accompanying drawings, Figure 1 shows in front elevation portionof a loom having applied thereto an embodiment of the invention, certainfeatures which are em- IOO . Another object is to suppress the action ofbodied in an electrical circuit being represented diagramatically. Fig.2 is aV View, partly in Vertical section, on line 2 2, Fig. l, lookingin the direction indicated by the arrows adjacent the ends of such line.Fig. 3 is a view in front elevation, showing mainly the weft-indicatormechanism and certain essentials of the unshipping appliances.

Having reference to the drawings, a a designate the end frames of aloom.

b is the lay, and b the reed carried'thereby.

c is-.the breast-beam.

dis ahopper or magazine corresponding substantially with. those of myLcttersPatent hereinbefore mentioned and constituting inf theillustrated embodiments of my inventionv the holder for the reservesupply of weft. Reserveshuttles are shown inthe said. hopper or magazineat e c. lnpractice these reserve shuttles will be filled with weft andinreadiness to be brought successively into service 1n carrying on theprocess of weaving. The instrumentalities by meansof which theweft-replenishing operations are performedv inpractice are or may besubstantially such as in the said Letters Patent, although it shoulda.be understood that the precise character of the holder and replenishinginstrumentalities is-not material.

My present invention bears a certain relationship to the weft-indicatormechanisml andv power-unshippingappliances ot'- a loom, although theprecisecharacter,construction, andl arrangement of these are notmaterial. Sufiicient of the elements of the said mechanism-andappliancesis shown in the drawings to render clear the manner in whichthese cooperate with the other features of which I shall treat herein.

Any ordinary weft-fork is shown at f and its carrying-slide at f', thelatter being mounted on. top of breast-beam c in the manner customary inweft-indicator mechanism of the common type. The gooseneck coperatingwith weft-fork f is-not shown, but will be arrangedk and caused tooperate as usual. It

will beunderstood that inthe running of the loom each time the lay beatsup after a flight of the workingV shuttle toward the driving endof' theloomA the weft, ify extending through the shed andl intact, will beborne against the tines` of the weft-fork, so as to cause the weftforkto tilt on its pivot and raise its hooked tail end above the path` ofmovement ofl the gooseneck-,whichlast is caused toyadvance atthisinstant in theworkingof they parts.

Thereby the gooseneck willi be prevented from engaging wi-th theweft-fork. It will .be understood also that. should theV weft be absentfrom in front of the tines of the weftfork at the time of the beat up ofthe lay and the advance of the gooseneck the weft-fork will be permittedto remain with its hooked vtail end within the path of movement of thegooseneck. This will enable the gooseneck to engage with the said hookedtail end, with :the result that the weft-fork slide f will be A drivenforward across the breast-beam. This advance of the weft-fork slidewillbe utilized in practice in a suitable manner to bring theweft-replenishing instrumentalities into action-for instance, as in myLetters Patent aforesaid.

An ordinary shipper-handle isshown-zatg.

At q is indicated the plate at onet end of.`

the breast-beam, having a slot in which the upper portion of theshipper-handleWorks,-

thev usual notch being formed adjacent one` endof the said slot toreceive the shipperhandle and retainit in pla-ce after thefpewer hasbeen shipped on during the runningiof the loom.4

g2 is a knocking-oft'- lever of usual character, pivotally mounted` atg3 on top of` the plate g and extending` inwardly beyond the.`

shipper handle. lltovement'y communicated to the said knocking-offlever'wilh causek the latter to actin the customary manner'topress theshipper-handle out of its*holding-notch,`

so as to allow it to effect thelunshippinggofithe loom.`

In carrying my present inventionrintoveffect l combine with the holderfortherreservey supply of weft devices to ascertain the condition ofvthe said supply. 'Fh-us` a movable feeler is applied to the hopperonmagazine CZ. This feeler in Figs. l and Zisconstituted yof aspringqarm. orI strip 7L, which is: secured to the front of the saidhopper ormagazine,m one portion thereof being; arranged to'proj ect.

inwardly into the hopper-or magazineinto position to coact with. thecontents of the latter. A reserve shuttlewithin the h'opperormagazine inpositionk to-act against the feelerwill press the latter outwardinto'its inoperative position. ln Figs. 1 and 2`the devices areelectrical, the feeler bei-ng utilized as afmeansf'off' The fe'el'er'controllingv an electric circuit. forms or carries onetermi'nal of thesaid` circuit, the other terminal being located'conven.-

viently, as at h,.on the hopperor magazine. The wires leadin gto thesaidterminals are'represented at h2 713, respectively,andi thesource ofelectrical energy is represented at h4,Fig. 1. So long as' the hopperor` magazine-.contains'a reserveV supply sufficient to meety theimmediate needs of the loom, suchsupply-bevingin proper position toenable replenishment to be effected, the circuit will'v be held, open orbroken between the two terminals hh.. Should, however, the reservesupply become depletedv to= the predeterminedl extent ora;

mitted to move, so as to occasion a closing of the circuit. For thepurpose of apprising the Weaver of the fact that the holder for thereserve supply of weft requires attention I include in the circuit asignaling device of suitable and approved character either audi-r ble orvisual. Thus at h5, Fig. 1, I have represented an electric bell.

Figs. 6 and 7 show a mechanically-operated visual signal which may becombined with the hopper c7. being in the form of a lever, which ispivoted upon a pin 7L?, provided on a bracket or stand 7L8,'fastened tothe front of the hopper or magazine cl. A spring 7L9 acts upon thefeeler hG with a tendency to force its lower end inward against thecontents of the hopper or magazine. A second lever 7t10 is pivoted uponthe front of the hopper or magazine at h1?. Itis Weighted at one end, asat h1?. and the other end thereof carries a target 7tlg in the shape ofa small flag. The upper arm of feeler h6 is furnished with a hook orlatch, as shown in Fig. 7, to engage with the signal-lever 7110. Therebythe signal-lever is held normally in the vfull-line position representedin Figs. G and 7. When the feeling end of feeler 7t` is permitted tomove inward into the hopper or magazine by the absence of a shuttleadjacent such end, the hook becomes disengaged from signal-lever h1",whereupon the weight h1'2 causes `the latter to assume the dotted-lineposition of Fig. 6, displaying the iag or other target 7L.

Usually, tho ugh not necessarily in all cases, the feeler is arranged inposition to coact with the reserve shuttle in the hopper or magazine,which is in position to be transferred by the replenishing instrumentalities to the lay. When thus arranged, the signal apprises theWeaver when thehopper or magazine has been emptied. It will be operatedalso in case a shuttle should become caught in the hopper or magazineand fail to descend into position to be transferred. In the event of notbeing able to give sufficiently-prompt attention to the reserve supplyof weft atter having been signaled as aforesaid it yis preferred thatthe weaver should arrest the working o-f the loom. lf he is near to theloom, thisof course may be effected by unshipping the shipperhandle. Forgreater convenience, however, I provide automatic uushipping appliancescapable of.

being brought into action at the will of the weaver, all as follows:

g4 is a projection or bracket with which the knocking-off lever g2 isprovided, and g5 is a buntermoving toward and from the front of the"loom, the said bunter being affixed to the lay-beam.

gis a bolt mounted movably on-an arm Q7, thclatter being pivoted beneaththe breastbeam at g8 and furnished with a weighted 4portion g, Figs. land 3, the action of which tends to keep the said arm in a position tohold the bolt at one side of the path of move- Thefceler is shown at716, itv

ment of the bunter g5. by arm Q7, acts on bolt gwith a tendency to pressthe same rearward on the arm.

g is an electromagnet conveniently supported from the breast-beam. Thearmature for this electromagnet is formed or carried by the armg. Thesaid electromagnet is embraced in a branch circuit connected with theelectric circuit already described. This branch circuit contains breaks,which normally are open. One of these breaksis arranged to be closedautomatically by devices coacting with the contacts of the holder forreserve weft, while the other is arranged to be closed bythe weaver. Theautomatic devices act to close the `rst break `on the ocv currence ofthe predetermined emergency in connection with the reserve. supply ofweft and prepare the way for stoppage of the loom by the closing of theother break by the weaver. The relations are such that until the rstbreak has thus been closed automatically the closing of the other breakby the Weaver will be ineffective to bring about a stoppage of the loom.'In the illustrated embodiment of the invention the branch circuitcomprises a wire 71.14, leading from wire 7a2 of the main circuit, a'eeler M5, corresponding substantially in construction, dre., withfeelerv 71, and applied to hopperor magazine dalongside said `feeler h,a terminal h1, with which feeler 7t15 cooperates, a wire 71,17, leadingfrom terminal 71,16 to electromagnet gu, and a wire 7L18, leading fromthe said electromagnet to a suitable push-button, switch, or the likehw,from which last a wire h2o extends tothe wire 7a3 of the main circuit.

So long as the feelers 7?. 71,15 are held pressed out by a reserveshuttle within the hopper or magazine', lbreaks are maintained at suchfeelers in both the main and the branch circuits. If underthis conditionof things pushbutton h1 is pressed upon by the weaver, the electromagnetat g11 will not become excited. When, however, the absence of a shuttlefrom `the hopper or magazine permits the feelers to move inwardly, thesaid breaks are closed.' One result of this is that the signal isoperated. The other is that if the weaver `after .observing the signalnow presses upon the push-button theelectromagnet g will become excitedand, acting to swing arm g?, will move bolt g6 in line with bunter g5.In the Vensuin g advance of the said bunter it will encounter the boltand drive it'forward against `projection g4 of knocking-off levergthere- 'by occasioning the disengagement of the shipper-handle g andthe unshipping ofthe loom. i

The foregoing devices provide for detecting automatically the occurrenceof a predetermined'emergency in connection with the re serve supply ofweft in a weft-replenishing A spring Q10, carried IOO IIO

loom and apprising the weaver of such oci currence by operating asignal, without, how- `ever, actually causing the immediate stopn pageof the loom. In addition they provide page, but which when the detectordevices.

ascertain the occurrence of such emergency thereby are rendered operableat the will of the weaver to bring about the stoppage of the loom. Thusthe weaver is apprised promptly of the emergency aforesaid by the signaldevice. This will enable him to take the steps which are necessary to betaken for supplying the needs of the loom. Also he is enabled at hisdiscretion, and especially if he is occupied elsewhere, to bring aboutthe arrest of the Working of the loom before exhaustion or failure ofthe working weft-supply occurs.

For the purpose of enabling the weaver to bring about at will the arrestof the particular loom in which need exists for attention to thecondition of the reserve weft supply, even when stationed at somedistant point among the group of looms under his charge, I connect thesaid group of looms into a series, as I now will proceed to explain. Thewires h2 h3 of the main circuit are extended throughout the entireseries of looms. To the wire h2 are applied bells h5- or other signalssufficient in number to answer for the series of looms, either one foreach loom or otherwise, as deemed advisable. Reference may be had toFig. 5. With the said wire h2 are connected also the feelers h of thevarious looms. The wire h3 has connected therewith all the terminals h.The wires h h2o ofthe branch circuit are extended throughout the seriesof looms. One of the said wires (shown as h2o in Fig. 5, to securesimplicity in the diagram) has all the push-buttons h19 in connectiontherewith, while the other of the said wires (h14 in Fig. 5) has all theelectromagnets h connected therewith. The wire 7117 is also eX- tendedthroughout the series of looms, it connecting in Fig. 5 with all thefeelers h15 and push-buttons h1". The slight difference in arrangementwhichis observable in Fig. 5 is adopted foi` greater clearness andsimplicity of diagrammatic representation.

From Fig. 5 it will be apparent that the closing of a feeler h againstits terminal h in any loom will cause the signals to be operatedthroughout the series of looms; also, that if the weaver presses upon apush-loutton h1" at any point in the series of looms this act will bringabout the stoppage of the loom in which feeler h15 is closed againstterminal h1G and of no other loom.

For the purpose of preventing the replenishing instrumentalities frombeing called automatically into play after the last reserve shuttle hasbeen transferred to the lay from the hopper or magazine d, I provide thefollowing devices: In Figs. l and 2, t designates an arm projectingbeneath the said hopper or magazine. A shuttle at the bottom of thelatter in readiness to be transferred to the lay by the action of thereplenishing instrumentalities bears upon the said arm and by its weightdepresses the latter, thereby rocking the shaft t', on one end of whichthe arm is made fast. The said shaft is mounted in bearings at the rearside of the breast-beam c and at the opposite end thereof carriesasecond arm i2. Through a hole in the latter passes the lower end of arod t3, which is hung to the weighted forward arm of a lever 4. Thelatter is pivoted upon the weft-fork slide f and its rear arm passesunder a projection from the tail of weft-forkf. A collar t6 on the rodt3 rests on top of the arm When a shuttle at the bottom of the hopper ormagazine d bears against arm t' and depresses it, rocking the shaft t"as stated, the arm t2, bearing upwardly the rod t3 and weighted arm oflever i4, thereby leaving the tail of weft-fork f 8 5 free to descend,as in the drawings, into the path of the gooseneck and to be engaged byY the latter when such tail is not raised by the action of weft againstthe tines of the weftfork at the beat up of the lay. When, however, noshuttle bears on arm t', the weighted arm of lever t* is free todescend, whereupon the rear arm of said lever lifts the tail end of theweft-fork out of the path of the gooseneck. This prevents the working ofthe weftindicator'meehanism, and consequently, inasmuch as suchmechanism is depended upon to call the-weft-replenishinginstrumentalities into action, suppresses t-he action of the saidinstrumentalities.
